SGS-CSTC Report: N77 Occupied Bandwidth Test Results

Appendix-B-44-4-6907891

This document presents a comprehensive analysis of the occupied bandwidth for the N77 frequency band, as tested by SGS-CSTC Standards Technical Services (Suzhou) Co., Ltd. The report, identified by number SEWA2309000114RG02, details a series of tests conducted under various configurations to ensure compliance with regulatory standards.

The tests cover a wide range of parameters, including different modulation schemes such as DFT-QPSK, DFT-PI2BPSK, DFT-16QAM, DFT-64QAM, DFT-256QAM, CP-QPSK, CP-16QAM, CP-64QAM, and CP-256QAM. The bandwidths tested range from 40 MHz to 100 MHz, with specific configurations like Full-106@0, Full-100@0, Full-128@0, Full-133@0, Full-162@0, Full-180@0, Full-189@0, Full-216@0, Full-217@0, Full-240@0, Full-245@0, Full-270@0, and Full-273@0. All tests were performed using Ant0.

The results presented in this report demonstrate that the equipment under test meets the required occupied bandwidth limits for the N77 band under all tested configurations. The report includes detailed spectrum analyzer plots and marker tables, providing a clear visual representation of the occupied bandwidth for each test case. The tests were conducted in accordance with established testing methodologies and procedures, ensuring the accuracy and reliability of the results. All tests passed the required criteria.
